[AMDGPU] Fix scan of atomicFSub in AtomicOptimizer. (#66082)
[D156301](https://reviews.llvm.org/D156301) introduced atomic
optimizations for FAdd/FSub. For FSub, reduction/scan needs to be
performed using add operation (`not sub`) and memory location will be
updated by reduced value using atomic sub later by only one lane.
